VENTILATING, HEATING, AND COOLING APPARATUS.

SPECIFICATION formingpartof Letters Patent N0. 761,581, dated MayBl, 1904.

Application filed January 8, 1901. S eria1No. 42,518. (N model.)

To aZZ whom it may concern:- I

Be it known that I, OfiARLEs OLUTHE, a citizen of the United States of America, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Ventilating, Heating, and Cooling Apparatus, ofwhich the following is a specification, reference "being had to the accompanying drawingsand the-letters of reference marked thereon.

The object of my invention is to provide an 'improved'syste'm and apparatus for the convenient and economical heating or cooling and Ventilating of rooms in a building, and I accomplish the objects of my invention by the construction herein set forth.

-In the accompanying drawings, in whichlike letters of reference indicate like parts,

. .Figurel is a sectional side elevation of my improved device, and Fig. 2a plan view of the same with the outlet-cover removed.

In the construction of my improved device .I. provide a case or box A, preferably of metal and suitably supported in an inclined" position, as shown in Fig. 1 The inclined;

position of the case and step-by-step arrangement of internal coils or radiators presently. to be described facilitates the circulation of the air in said case where the device is employed as afheater, since hot air rises, and

when used for cooling purposes this arrangement affords means for forming a coolingvchamber or refrigerator beneath the case by inclosingthe space below the same.

7 Within the case A, I arrange a series of pipes, coils,

or radiators b, the top of each succeeding set. extending above the top of the set preceding, beginning at the left-hand end, as shown. Between each pair of sets a deflecting plate or partition'C is introduced, one series depending from the top' of the case and the other series rising from the bottom thereof, the upper and lower plates alternating with h each other. The plates C extend only part way between the top and bottom of the case -A, and the air in its passage through said case is compelled by said plates topass in a tortuous course, and thereby brought into close contact with the coils b to be heated or cooled,

A according to the purpose for which the apparatus is employed at the time.

An air-inlet conduit D extends from the lower end of the case A'to a point outside of the building, where it opens, andto avoid Varying pressure occasioned by differences in the force and direction of the, wind plates 0 are provided in the outer terminal of said conduit, said plates'being arranged'in a similar manner to the'plates O. Now when the wind blows toward the exposed open end of the conduit C an objectionable rush of air through said conduit is obviated, as the plates 0 check the air and preventit from passing into the case A with undue force. V

A receptacle (2 is formed above or over the highest part of the caseA, which opens into the same. This receptacle is supplied with a coil 0, on which is placed awater-reservoir or evaporating pan f of any suitable construction which will allow for the passage of air around, through, or over the same. The form of pan f shown in the drawings is considered to be as good as any, and by preference it should ,rest upon-the coil 0, although this is not imperative. A trough 9 opens at oneend into the pan f and extends therefrom through the side of the receptacle 0? beneath a faucet h, which is adapted to supply waterthereto drop by drop. To avoid danger of overflow resulting from the. accidental supply of more water than is taken up by evaporation, an overflow-trough a opens into the pan f at one end and over a waste-trough j at the other end I The overflow-trough serves to prevent the water in the pan f from rising to theheight where it would flow over the walls of said pan onto the parts-below. The receptacle d is closed at the top by a cover is, having openings in its sides to which pipes Z are fitted and the pan f or the vapor arising therefrom before escaping into the pipes l.

When my system and apparatus are to be employed for heating purposes, heat may be supplied tothe radiators or coils Z) and e in any convenient and suitable manner, an ordinary steam-heating boiler of the low-pressure type being preferred and indicated at E in Fig. l. A live-steam pipe at connects the boiler E with the nearest radiator-or set of coils b, and the steam after circulating through all of the coils 7) and the coil 0 returns to said boiler through a pipe m. Through the medium of the parts previously described the air which enters the conduit D circulates fully and freely about the radiators b, then rises to receive more heat from the coil 0 and to commingle with the moisture above said coil, and finally passes at a proper temperature and sufficiently moistened through the pipes Z to the several rooms. The construction and arrangement of the parts insure adequate and complete circulation throughout the apparatus and rooms, as well as proper heating and moistening ofthe air. During warm weather I disconnect the boiler or other heat-producer from the coils and connect the latter with the water system of the buildingin order to utilize my invention for cooling purposes. As an illustration of means for carrying out this plan a pipe 1) is shown in Fig. 1, which communicates with the water-main and the pipe m, and a pipe p, which supplies the building with water and is connected to the pipe 177/, the pipes 12 and 2 being provided with valves 0 and 0, respectively. The change above referred to is effected by closing a valve or in the pipe m and avalve n in the pipe m and opening the valves 0 and 0. As practically no flow of air through the apparatus will take place naturally in the absence of heat from the coils, a fan (1 (indicated by dotted lines in" Fig. 1) is placed in position in the conduit D near its junction with the case A and any well-known means employed to run the same. A door D is arranged at the side of the conduit D to facilitate the insertion and removal of'the fan. Of course the fan may be located in some other place, if desired. The fan q forces the air which the conduit D receives from the outside into and through the case A and the receptacle d, around and through the coils b and e, which are now cooled by'the water therein, over and about the Water+pan f, and finally through the pipes Zto the rooms, the circulation being thorough and complete,! as before, with the air properly cooled and moistened to meet the requirements incident? to hot Weather. It will readily be seen that by connecting the coils with the water system at a point between the supply and delivery the cooling effect of the water may all be utilized without expense, because the amount of water usually drawn is sufficient to change the contents of the coils frequently enough to answer the purpose. If, however, a greater cooling effectis required, it is only necessary to open a faucet and allow a small quantity of water to In order to meet the requirements of different altitudes or variations in degree of dryness or humidity, it is necessary to provide means to regulate the supply of water to the pan fiand such means is found in the faucet h, which controls the flow of water from a suitable source of supply. By supplying as much water only drop by drop to the heated pan f as Will all evaporate I am able to meet the requirements of high altitudes or d ry atmospheric conditions, while at low altitudes or under humid conditions the drop-by-drop feed is sufiiciently increased to keep more water constantly in said pan than will entirely evaporate, or, in other words, to supply enough water to lower the temperature of the pan, and consequently decrease the evaporation. These different conditions of outside atmosphere can be readily and successfully et, so as to insure a substantially uniform. impregnation with moisture of the air on its way to the rooms, by turning the faucet It to increase or decrease the amount of drip into the trough g and thence into the pan f.

While the plates C and c are shown and described as being placed in a vertical position,

-it will be understood that they may be arranged horizontally Without departing from thenature of my invention, although by preference the plates 0 should stand as shown when upright coils t are used. Furthermore, there would be no violation of the spirit of my invention in placing the coils & in a reclining position. These and other minor changes within the limit of mechanical equivalents may be made, if deemed expedient, and an arrangement of the aforesaid plates whereby they are placed horizontally is considered to be such an equivalent of the plates 0 and c.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with a case A, of a series of coils arranged therein in a step-by-stcp manner, an upper series of plates, a lower series of plates, both series being arranged in said case between said coils, and the plates of one series alternating with those of the other, whereby to cause air to traverse a tortuous course through the case, means to force air into the case at one end, pipes arranged to conduct air from the opposite end of the case to the rooms of a building, a horizontal coil with a superimposed water-pan located between the upper end of the case and the outlet-pipes, substantially as set forth.
